BED-SPRING TIGHTENER.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed May 6, 1909. Serial No. 494,281.

To all whom it may concern:

Be it known that we, SILAS W. BENNETT and ELMER N. HUToHINs, citizens of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Bed-Spring Tighteners; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bed spring tighteners.

The object of the invention is to provide an improved construction of bed spring supporting and tightening devices and means whereby said devices are held in position and engaged with the rails or corner posts of a bedstead.

A further object is to provide a spring supporting and tightening mechanism adapted to form part of a bedstead or couch frame.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side view of a spring holding and tightening mechanism. constructed in accordance with the invention and showing the same applied to a bedstead; Fig. 2 is a sectional view on the line 2-2 of Fig. 1; Fig. 3 is a detail. view of the castings at one side of the foot end of the bed, taken at right angles to and on the line 33 of Fig. 1; Fig. 4 is a detail sectional view on line 4-4 of Fig. 1; Fig. 5 is a detail sectional view through the spring holding and fastening bars at the foot end of the bed, showing an inner side view of one of the foot castings; Fig. 6 is a side view, with parts removed of a modified form of the invention, wherein the spring holding and tightening frame forms part of a bedstead or couch; Fig. 7 is a ver tical sectional view on the line 7-7 of Fig. 6; with the parts in place. Fig. 8 is a similar view on the line 8-8 of Fig. 6; Fig. 9 is a horizontal sectional view through one of the head castings shown in Fig. 1 and the parts attached thereto. Fig. 10 is a side view of the form of the invention shown in Fig. 6 illustrating the manner in which the invention may be employed to form a series of beds one above the other. Fig. 11 is a sectional view of one of the beds shown in this figure taken on line 1l11 of Fig. 10.

In the embodiment of the invention, we provide a frame comprising head castings 1 having formed therein sockets 2 and 3 which are arranged at right angles to each other, as shown. On the castings l is also formed a base flange 4 adapted to engage or rest on the side rails of the bedstead, said base flange 4 having on its inner end a stop lug 5 to prevent the frame from slipping off of the side rails of the bedstead. The sockets 2 are adapted to receive the tubular side bars 6 of the frame, while the sockets 3 are adapted to receive the ends of tubular cross bars 7 which connect the two head castings together. The castings 1 are further provided with laterally extending brackets 8 which form a continuation of the sockets 3 and to said brackets 8 are bolted or otherwise suitably secured the opposite ends of the tubular cross bars 7. The castings 1 are also provided with upwardly and outwardly projecting roll supporting brackets 9 in which are formed annular bearing apertures 10 and a series of radially projecting notches 11 which communicate with the bearing apertures 10, as shown. In the bearing apertures 10 are revolubly mounted short roll supporting and winding shafts or trunnions 12 which are provided with flanged heads 18, said heads having formed therein oppositely disposed notches 14: which are adapted to be brought into alinement with the notches 11 in the brackets 9 and into the alined notches 11 and 14 are inserted keys 1.5, by means of which the shafts or trunnions are held against rotation in the bearings 10. The heads 13 are also provided with retaining lugs 16 which, when the trunnions are engaged with the bearings 10, are passed through one of the notches 11 and engage the inner sides of the brackets 9, thus holding the trunnions or shafts 12 in operative engagement with the brackets. In the inner portion of the trunnions or shafts 12 are formed oppositely disposed slots 17. The inner ends of the trunnions or shafts 12 are adapted to be inserted into the opposite ends of a spring tightening roll 18 through which, near its opposite ends are arranged bolts or pins 19 with which the slots 17 in the ends I operating ofthetrunnions are engaged, thereby look.-

,ing the roll against rotation on the inner ends of the trunnions In the outer ends of the short shaftsor trunnions 12 are formed square sockets 19to receive thejend .rofan crank or wrench whereby the tightening roll is revolved in the bearing vided-on theirinner sides with sockets 22 brackets 9; a

The rear ends of the slde bars '6; are supported in foot castings 20 which are pro .vided with sockets 21 to receive said ends of the side bars. The castings 20 are also pro- L which are arranged at right angles to the a are; provided. with bedstead; On the castings are formed: I upwardly and rearwardly projecting brack- 7 ets 26, on the upper ends of which are formed sockets to receive the ends of a tubul'ar spring holdingbar 27 to which the foot endv of the spring 28 is secured. The

spring 28" is preferably secured to the tight eningroll 18by an angle iron fastening bar '30 which is bolted or otherwise secured-to .:the roll, as shown; The angle iron bars 29 end of the spring is preferablysecured to the holding bar 27 "by *means of an angle iron bar'29 which is bolted or'otherwisesecured to fthe bar, as shown. The head end of the alsoserve to brace the bar 27 and the roll 7 18 so that said roll 'and'bar may resistthe strain of the. spring when stretched by'the tightening V mechanism, hereinbefore described. V i

In Figs-G, 7 and 8 of the drawings are shown'slightly modified forms of the frame T supporting castings.

a and foot ends of the frame. The head cast-:

The head .castings3l and footicastings 32, as shown in the'last mentioned figures, are provided on one end with ,fit around the corner posts or legs of the a postengaging recess 33 whichis adapted to bedstead and are bolted to said posts or legs by bolts 3 1 which are inserted through the posts or legs and through apertures in the ends of the castings, as shown. The castings 3l and 32 are provided with sockets 35 and 36 which correspond with the sockets in the castings shown in the first figures of the drawings and are adapted to receive the ends ofthe side bars 6 and cross bars at the head I vings ;31'are-' provided with roll .supporting brackets 37 which correspond to the bracki ets 9 shown in the first figures of the drawrings, except that the brackets 37 project directlyupwardly from the castings or are in a verticalpositi'on. The brackets 37 are provided with bearing recessesto'receive the spring tighteningroll and its operating and locking mechanism which is the same as that shown'in Figs. 1 and 2 of the drawings. The foot castings 32 are provided with brackets 38 which receive and support the spring holding bar at the foot end of the frame, the same as described in connection with the first figures of the drawings.

, The spring frame shown in Figs, 6, 7 and 8, isadapted to form a part of the bedstead and by the use of the same, the side and end rails of the bedstead are dispensed with.

The castings 31-and-32 arealso provided withrail engaging flanges 39 by means of which this form of frame may be employed simply'as a spring support and may be engaged with the side rails of the bedstead.

' It will be obvious that the form of the frame shown in Figs. 6, 7 and 8 may be employed as a part of a couch frame, as well as a part of a bedstead and that the frame may be supported by legs to which the castings 31 and 32 are bolted in the same manner as they are bolted to the corner posts of the bedstead. The side end bars of the frame, as well as the spring holding bar and winding roll are preferably tubular in form, as shown.

In Fig. 10 of the drawings the device is shown as arranged to form'a series of beds one above the other,'the form of castings 31 and 32 shown in Fig. 6 being employed in connection with this arrangement of the device, except that the brackets 40 of the foot castings 32 which correspond with the brackets 38 of Figs 6, 7 and 8 are provided with angular sockets 41 to receive an angle iron spring holding bar 42 to which the foot end of the spring isattached. In this form of the invention the spring fastening bars 29 and 30 are omitted from the head and foot spring holding bars and the ends of the spring secured direct by the holding bars in any suitable manner.

From the foregoing description, taken in connection with the accompanying drawings, theconstruction and operation of the invention will be readily understood without rcquiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claim. I
